I am mounting it on a Canon 5D and a Canon 60D. Not having much luck though and the focal length is incredibly short, and can only focus on things about 50cm in front of the lens, with a very thin focal length even then. I have a fairly thin (5mm) "air" adapter, which I know will not focus to infinity, but as it is, these lens are practically unseable on my Canon bodies.

What are you Canon guys using to successfully use these lenses? or are Canon bodies simply just not a good match to these lenses due to the depth to the sensor?

I will try one of the adapters that allow focus to infinity, but by all reports these significantly degrade image quality due to the cheap glass in them. Does seem like my only real option at the moment..

everybody shooting these lenses on canon is using lenses that have had mount conversion, meaning the minolta mount was removed and replaced with a custom made eos mount. they won't really work for anything other than macro if you're just adapting. unfortunately the two lenses you have are extremely difficult ones to due the mount conversion on. i believe jim buchanan from this forum has converted the 50/1.4 (at least one version of it) though.

anyway, here is a shot from the 58/1.2 on a NEX-7, unfortunately with some motion blur, but i still like it:

Thanks for the advice. Yes, I did have a look and believe I may be able to pull it apart and replace it with a Canon mount with some work, but I guess that will destroy the lens as adaptable to other cameras.. I am actually thinking of purchasing a Sony Nex 5R in the next 12 months for the smaller and easier carry factor than the a full sized slr, so I guess I had better decide what I want to do.

fyi - both those lenses have a bunch of the aperture control levers attached to the back of the mount. if you want to maintain aperture control you need to either destroy the old mount to make the new mount or replicate all those levers yourself. if you aren't fairly skilled with a mill and a lathe i would advise against trying to do the conversion yourself.

Here are three with the Rokkor 58/1.2, the first one at ~5.6, the second at 2 or 2.8 and the last wide open. I have had this lens for some time now but haven't gotten around to use it much, hopefully this will improve.

As has been said, conversion is about the only real method to mount them on EF bodies, the adapters with elements just don't do justice to these lenses. and they basically act like a tele converter from what I understand....

I did have a 58/1.2 converted to EF, and used it on my 1DIII very regularly, Then I bought a converted 28/2, and I was about to convert the rest of my Rokkors, since I can still adapt them using EF to what-ever adapters, then I got the NEX 7, and my decision was made to keep them stock, I returned the 58/1.2 to stock since it was a mount swap and I have all the bits that came off it, the 28/2 will stay EF since it was a permanent conversion.
....I've been using them for a while now on my NEX-7 and I do enjoy the experience, I do wish the sensor was FF, so I'm crossing my fingers that Sony or someone else releases a FF mirrorless with an EVF this coming year, ie. a NEX-9.

Fantastic shots everyone! I just want to share the hood I "made" for my 58/1.2. It's made of a 55-67mm step-up ring and a 67mm metal tele hood. It's chopsuey, bu it does the job until I find a d57kb hood. It doesn't make vignetting any worse too. I found that a hood is just essential to this lens.

Oh btw, the red rubber ring helps with the grip. It's a rubber bracelet. I could have used black but it's the only one I found laying around

These are very poor. Camera shake or motion blur all over, there's almost no in-focus areas, and the composition leaves something to be desired.

I know the lens is decent so...

What happened?

handheld macros in poor light. focus was less than a centimeter from the front element. there is a fair bit of motion blur (camera and subject), but i suspect the lens also wasn't designed to handle such a short focus distance. i was mostly curious to see how dof and angle of view looked with such a wide lens for macro. i don't think you can get anything other than abstracts at such a short focus distance.

Ah... I see.

Nah, it's not like that. Go check his other work and you'll see.

But I do kinda wish the audience here were tougher! FM used to be like almost all pro level work with only a few such as myself, outside the gates of awesomeness. Now the vast majority or work being posted are weekender snapshots. Very saddening!
